Slice it Up is a tool that cuts artwork into any number of vertically aligned slices by duplicating it N times and applying clipping masks to it. Those pieces are combined into one group and laid one over another to create undistorted image. Tool provides controls to set random or linear offset to X and Y position for each slice, adjust the expansion and rotation angles for the clipping mask.

Select a layer you wish to slice and run the script. Enable “Preview” checkbox for live feedback. Enter desired value for slices, Adjust sliders for X and Y axis distribution, select Container Mode and you’re done. Press “Slice it Up” button to confirm.

By default slider values are limited. However, if you feel that provided values does not suit your need, then enter custom values to edit box field. That should get you covered.

You will find one group layer that holds all the slices once slicing is finished. All is nice and dandy, but for the sake of safety select that group and run “Merge” or “Trim” command from Path Finder menu. This way each slice will be trimmed to its content.
